Slack

​

What It Does

• fetches messages from one or more Slack channels
• indexes each message and each thread reply as a separate document in the vector store
• resolves channels directly by ID or dynamically via name patterns or regex
• optionally restricts ingestion to a date range
• attaches channel name and resolved username as metadata on each indexed message
• skips system/bot messages (channel joins/leaves, file shares, thread broadcasts) — only actual message content is ingested
• runs ingestion on configurable schedules

​
